NUT LOCE.

Application filed May 5, 1922, Serial No. 558,569. Renewed October 17, 1923.

To ZZ 1o/wm t may concern:

it lrnown that l, dosnri-r BARNES? a citizen o'fv United States, residing at Clark, in the .county of Randolph, State ot Missouri7 have invented certain new and useful 'lmprcvenxcnts in Nut Locks; and l do hereby declar the 'following' te be a it'ull, clear7 and exact description or the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and usetul improvements in lock nuts1 and is especially adapted for use in connection with rail joints, while other equally advantageous uses may be made et the nut.

@ne object of the invention is to provide a nut so constructed that one or more et the corner portions may be bent by the blow oi3 a hammer out ot its normal plane so as to bite into the surtace ot the work.

Another object is to provide a nut of this character which has means other than the corner portions for biting into the surface of the work to effectively prevent rotation oit the nut in either direction7 atter having been properly driven home.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

ln the drawings:

Figure l is an eleva-tion of the nut in connection with a bolt and a plate, showing the nut in locking position.

4Figure 2 is an inverted perspective view ot the uut.

Referring particularly to the accompanying drawing l() represents the body of the nut having the usual threaded opening ll therethrough for engagement on the bolt l2. Formed diagonally across the inner or working tace of the nut is a rib 13. which is adapted to engage against the work lsf, and thus hold the nut body spaced a short distance Yfrom the work. Formed integrally ou its inner tace and adjacent the other two diagonally opposite corners are the pointed lugs l5.

After the nut has been screwed home7 that is.7 until the rib 18 rmly bears against the work 11i, the diagonally opposite'corners which carry the pointed lugs l5 are struck with a hammer so as to bend them inwardly against the work tace la, and out ot the original plane ont the body cit the nut. rlhe said corner portions will bite into the work let as will also the lugs l5, thus elle@ tively holding the nut against turning7 in either direction, on the bolt, due to any jarring or moving of the parts with which the device. is used.

W hat is claimed is: n

l. A locking nut comprising an angular body, means on the working face of the body Vtor spacing certain Corner portions of the body from the tace of the work, said corner portions normally in the plane of the body being bendable out ot the said plane in the direction of the work.

2. A locking nut comprising an angular body having means for contacting with work to space certain corner portions from the tace off the work, said corner portions normally in the plane et the body being bendable by the blow oit' a tool out of the said plane and into contact with the work.

3. A locking nut comprising an angular body having corner portions normally lying in the plane or the body and bendable out ot the said plane, and means forminga part of one tace ot the body to provide a fulcrum on which the corner portions are bendable.

e. ,fr locking nut comprising an angular body having a transverse rib across its working tace with the corner portions at opposite sides of the rib lying in the plane ot the body and bendable out ot the said plane.

5. A locking nut comprising an angular body having a rib extending diagonally across its working tace between two corners thereof and with the remaining corner portions lying normally in the plane of the body and bendable out of the said plane.

61A locking nut comprising an angular body having rib extending across the working tace between two diagonally opposite corner portions, the remaining corner portions being normally in the plane or" the body and bendable out of the said plane and into Contact with a piece of work.

7. .ti loci-:ing nut comprising an angular body having a rib extending across its working tace between diagonally opposite corners, certain other of the corner portions being normally in the plane of the body and bendable out oi the said plane in the direction otthe rib, and work penetrating means on the working faces of the bendable corner portions.

8. locking nut comprising an angular 'the biting lugs into engagement With the work.

In testimony whereof, I aix my signature, in the presence of two Witnesses.

JOSEPH B. BARNES.
